VectorWare got SIMD on GPU to run with the same Rust code already used on CPU, compiling core::simd directly to warp instructions. The finding builds on their earlier work porting std::thread to the GPU.

A benchmark by Jeff Geerling shows that the Dell XPS 13 with Intel Core 5 320 beats a MacBook with Apple Silicon in energy efficiency: 6.21 versus 5.38 Gflops per watt. The full results are published on GitHub so anyone can reproduce them.

A 13th-century magical treatise promised to transmit all university knowledge through diagrams and prayers, without years of study. An essay from The Public Domain Review reconstructs its history, its condemnation by Thomas Aquinas, and its unexpected parallel with today’s promise of artificial intelligence.

AMD and Meta ported PyTorch Monarch, the single-controller runtime for distributed training, to Instinct GPUs with ROCm. The system isolates failures by actor and lets the cluster keep training even if a node goes down, without restarting the entire job.

Learn WebGPU for C++ is open source documentation that teaches native 3D graphics programming in C++, using the same API that runs inside browsers. It covers Windows, macOS, and Linux with CMake, and lets you choose between the wgpu-native and Dawn backends. The same native code also compiles to WebAssembly with Emscripten.

QuadRF is a phased array radio built on a Raspberry Pi 5 that detects WiFi networks through walls and tracks drones in flight. Jeff Geerling tested it for a week and confirmed it works even in its pre-production version.
